甘愿坐穿“冷板凳”

2017-08-10 06:38:44   中国青年网

乙烯作为世界上产量最大的化学产品,在国民经济中举足轻重。压缩机是乙烯生产设备的“心脏”,有着“压缩机一响,黄金万两;压缩机一停,效益为零”的说法。在西方跨国垄断巨头的眼里,大型乙烯压缩机是他们怀里的宝贝,是国家间较量的砝码,核心技术一直秘不外宣。

一位中国女子成为跨国垄断的终结者,用10年时间走完了西方国家在压缩机领域100年的路。她就是沈阳鼓风机集团公司设计院副总工程师姜妍。姜妍不仅主导设计了我国第一台乙烯压缩机,还是我国百万吨乙烯压缩机设计第一人,使我国成为世界上第四个具有百万吨级乙烯“三机”设计制造能力的国家,彻底终结了我国乙烯压缩机长期依赖进口的局面,奏响了“大国重器”绝不假手于人的科技强音。

成绩一大堆,没想到姜妍先说的却是失败经历。她说自己承担的头一项大任务就搞砸了:那是给华锦乙烯设计中国第一台45万吨乙烯压缩机,这在国内没有先例可循。她和研发团队埋头苦干3年,成品出来了,试运转也没啥毛病,可一到用户那里实地运转就“炸了锅”。

原来,压缩机组的核心——转子,不仅要保持高速运转,还要适应温度变化,且要将振幅稳定控制在25微米以内。眼看着第一台压缩机转子在低温状态下振幅越来越大,用户急得把电话都摔了。投资上百亿元的乙烯项目,“心脏”停跳了意味着什么?每天损失数百万元。停产超过一个月,整个领导班子都得集体被免职。

用户给沈鼓20天时间整改,整改不好就全部退货。那意味着沈鼓代表中国冲击乙烯三机的研发将告失败。那段时间,一向开朗的姜妍在单位一直沉默寡言,回到家就再也压抑不住眼泪。同样顶着巨大压力的沈鼓领导却不断给研发团队打气:“世上哪有随随便便的成功,如果成功,成绩是你们的;如果失败,企业承担责任!”压力,能挤出泪珠也能憋出灵感。姜妍和团队逐一查找技术缺陷,最终在限期内攻破了超低温运行转子结构的核心难题,成功保障了国产第一台乙烯压缩机的稳定运行。姜妍破涕为笑。

一炮打响后,国家给沈鼓下达了三个百万吨压缩机组的研制任务。集团将任务交给了姜妍和她的团队。姜妍带领的团队,平均年龄不到30岁。研制过程中,她对团队里的人打基础、压担子,不看来路背景,一视同仁。有风险,她打头阵,敢打敢拼。经过不断优化,姜妍带领团队陆续攻克了转子结构等诸多难题,团队独创出缸内加气法,在性能和效率等方面都优于国外机组。2011年2月22日,中国首台百万吨级乙烯压缩机试车成功。“只有我们这些一线的科技人员吃得下苦、把‘冷板凳’坐穿,我们国家才能在国际竞争中挺直腰杆。”姜妍再次激动地流下了自豪的泪水。

如今,姜妍带领的创新团队设计创新产品已占到沈鼓集团总产品的60%。姜妍本人先后荣获全国优秀共产党员、全国劳动模范等称号。
